According to the ENT who has a background in neurology said that I stretched a nerve due to opening my mouth to wide for too long. When the nerve is stretched it can affect your tmj muscle which is across your cheek and behind your ear. She said it would go away in time and to massage the areas. The area is not as tight but im still need tooth 15th replaced and that might be causing strain on my muscles as well. Another problem I have is the nose stuffiness, its been so diffucult, Ive been off the nasal spray but probably caused more damage to my nose. This all started from a botched root canal done last year in Feb. Life has been hard. IM going to another ENT in Los ANgeles to see what I can do, it sucks not to breath normal.
